Settings / NMEA & AIS / Advanced / Ntrip

This feature allows you to access RTCM (SC 104) differential GPS data using Networked Transport of RTCM via Internet Protocol (Ntrip).

Ntrip allows this device to download RTCM corrections and then deliver them to your PPU. RTCM corrections provide differential GNSS data to your PPU, in order to improve accuracy. This can eliminate the need for your PPU to have an internet connection.

This feature requires (1) an Enterprise Subscription, (2) support from your PPU, and (3) an account with an Ntrip server providing RTCM corrections for your area. An Ntrip server account is not included with your Enterprise Subscription. It should only be used after first consulting your PPU vendor to confirm support for this feature. For some PPU's, you may require a special model or firmware update.

Settings

• Enable (Only SEAiq Pilot) : This switch turns on Ntrip support.
• Type (Only SEAiq Pilot) : Select the type of connection to make. Currently, version 1 and version 2 (the default) are supported. With either version, only connections via TCP are supported.
• Host (Only SEAiq Pilot) : This is used to set the IP address of an Ntrip server. You can specify either a hostname or IP address (decimal and dot). IP addresses are preferred because they do not require a Dynamic Name Server (DNS) to be configured.
• Port Number (Only SEAiq Pilot) : This is used to specify the port number for your Ntrip service. The Ntrip default port is 2101. A port is an integer number in the range 1-65535.
• Mount (Only SEAiq Pilot) : Select mount to use with this Ntrip service. You can also select this by viewing the source table after connecting.
• Status (Only SEAiq Pilot) : Current status of your connection to the Ntrip server.

Authentication

• User Name (Only SEAiq Pilot) : Use this username to login to an Ntrip service.
• Password (Only SEAiq Pilot) : Use this password to login to an Ntrip service.

Diagnostics

• Source Table (Only SEAiq Pilot) : This lists a table of Streams, Networks, and Casters reported by your server.
• Diagnostics (Only SEAiq Pilot) : This shows diagnostics describing the current status of your configuration.

Optional PPU Setup

• Enable (Only SEAiq Pilot) : This switch enables manual network configuration where RTCM data is delivered. For many devices, this can be disabled and the normal NMEA connection will then be used. The Trelleborg CAT MAX device requires enabling this feature.
• Host (Only SEAiq Pilot) : This is the IP address for your Ntrip PPU target. It is required for both TCP and UDP based operation. The host must be given as an IP address (decimal and dot). DNS hostnames are not allowed.
• Port Number (Only SEAiq Pilot) : This specifies the port number for your Ntrip PPU target. It is required for both TCP and UDP based operation. A port is an integer number in the range 1-65535.

• Connection Type (Only SEAiq Pilot) : This selects whether to use TCP (the default) or UDP when delivering RTCM to the PPU. Most devices only support TCP.

  Products that support UDP include Trelleborg CAT MAX.

  Note that for UDP, the port number and IP address are both required. The port number corresponds to the PPU port to send the data to.

• Status (Only SEAiq Pilot) : Current status of your connection.
